3 plug ecu.

[bikerdude0269]

I was looking at my ecu today on my 89 festy for my swap eventually.And it has three plugs going to it. From what I have been reading in the search this is the one that you need. I guess my 89 is a later in the year car after they quit the two wire plugs.

correction just found out I need 4 plug ecu, instead of 3 plug one.
